Having a chronic disease and eating gluten-free for a long time, I've been diligently searching Vegas for bakeries that are GF-friendly. I have to say that Beau Monde is a treasure that's hidden on the cross streets of Buffalo and Smoke Mountain. You'd drive right by if you didn't know as the signage isn't the greatest.
I've tried most of the desserts - the cake pops, the cupcakes, etc. But I have to say that my favorite is the Carrot Cake. It tastes just like the real deal! Highly recommended.
I tried some GF buns with some pulled pork and they were just so-so. I haven't tried the other breads.
